With the development of technology, when the reciprocating compressor adopts a very poor structure, the connection of two pistons becomes the key of the service lives of a supporting ring and a piston ring. The existing connecting method is likely to cause the increase of the coaxiality deviation of the first piston and the second piston if the coaxiality deviation of the first piston and the second piston exists during assembly. Resulting in increased localized wear of the piston ring and the carrier ring. The replacement cycle of the piston ring and the supporting ring is shortened. The use is inconvenient in contrary to the requirement of continuous and stable operation of the equipment.

Aiming at the defects of the prior art, the utility model provides a radial floating connecting piston of a differential compressor, which solves the problems that when a reciprocating compressor adopts a very poor structure to run, a first piston and a cylinder body are easy to cause due to the installation of the piston, and a second piston and the cylinder body are relatively high in coaxiality, so that a supporting ring and a piston ring are worn out in an accelerating way.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: the radial floating connection piston of the differential compressor comprises a first piston and a second piston, one end of the first piston is connected with a flange surface of the second piston, a flange hole is formed in the flange surface of the second piston, an adjusting pad is arranged in the flange hole, a positioning plate is arranged on the outer side of the flange surface of the second piston, and the positioning plate is in bolt fastening connection with the adjusting pad and the first piston.
Preferably, the thickness of the adjusting pad is larger than the thickness of the flange surface of the second piston.
Preferably, the outer diameter of the adjusting pad is smaller than the inner diameter of the flange hole.
Preferably, the first supporting ring and the first piston ring are respectively sleeved on the first piston.
Preferably, the second piston is respectively sleeved with a second supporting ring and a second piston ring.
Preferably, the bolt is also sleeved with a locknut and a gasket.
Advantageous effects
The utility model discloses a radial floating connecting piston of a differential compressor, which has the following beneficial effects: the utility model fastens and connects the first piston, the adjusting pad and the locating plate by bolts and nuts, meanwhile, the second flange surface of the piston is in proper clearance fit with the first piston and the locating plate, a radial clearance is arranged between the outer diameter of the adjusting pad and the second flange hole of the piston, thus the second piston can float radially relative to the first piston, the piston and the cylinder have better coaxiality, the radial deviation caused by poor coaxiality of the two pistons is avoided, the service life of the piston ring and the supporting ring is prolonged, the stop frequency of the reciprocating compressor for replacing the piston ring and the supporting ring is reduced, the utility model has considerable economic value, and the utility model has simple reinstallation and high repeated locating precision after disassembly.
